Hellboy Slot Game Review

Unleash the supernatural with the Hellboy by Microgaming, released in January 2010. With its RTP at 96.5%, the game offers a high volatility environment.

Featuring a 5-reel, 20-pay line layout, the Hellboy slot machine suitably caters to all bet ranges — from the minimum bet of $0.01 up to the maximum limit of $25.00. You’ll be eligible to win up to $25,000.

Driven by a unique comic-book-style design with hellish overtones, the game encapsulates visual interest effectively, providing thrill seekers with an engaging platform.

Read on this most recent Hellboy slot review. Immerse yourself now and experience the dark marvel that is the free Hellboy slot game!

Gameplay and Mechanics

One of the machine’s most compelling features is the ‘Underworld Bonus’. Triggering this involves the appearance of three or more scatter symbols.

Additionally, the ‘Supermodel’ randomly grants players 10 free spins, allowing the potential for higher rewards.

Embark on an exciting journey with the game by choosing between the free demo mode and the real-money version.

To kickstart the game, you must adjust your bet for each spin, with a minimum of 0.01 credits and a maximum wager of 50.00 credits available.

Once your bet is set, it’s time to click the ‘Spin’ button and dive into the action. As the reels start spinning, you’ll encounter familiar Hellboy symbols, including

  • Hellboy
  • The game logo
  • The Iron Fist
  • 10
  • J
  • Q
  • K, and
  • A
  • Liz Sherman.

The Hellboy paytable is as follows. You’ll need to land three identical symbols arranged from left to right to claim your winnings. The coveted game logo represents the most substantial prize, granting an impressive 10,000 credits when you align five of them on the reels.

Hellboy and Liz are two more high-value symbols, offering generous rewards of 5,000 and 2,000 credits, respectively, when you land five matching symbols of each.

Landing five professors on the Hellboy paylines will bestow a generous 500x line bet multiplier, while Johann Kraus and Abe Sapien are even more rewarding, offering 750x and 1,000x, respectively.

Witness Liz Sherman igniting your winnings with an impressive 2000x line bet multiplier when you secure five in a row. At the same time, Hellboy propels your rewards to new heights with an astounding 5,000x multiplier.

Hellboy Features to Admire

  • Supermode: During Supermode, three wild positions are selected randomly and remain fixed throughout the bonus round, potentially leading to some substantial winnings.
  • Underworld bonus, which gets triggered when three or more scatter symbols appear. This bonus presents itself as a mini-game, where the objective is to locate your team of anti-heroes before embarking on a seemingly endless tunnel, which would prematurely conclude the bonus feature. Accomplishing this task allows you to advance to the next level.
  • Relic of Power: To claim the ultimate reward, you must conquer all four levels and reach the Chamber of Fire when playing Hellboy.
  • Gamble Feature: The game’s emblem, too, presents a colossal jackpot potential, offering players the chance to score up to 10,000 credits, a bounty that can be multiplied by two or even quadrupled if the player decides to engage the ‘Gamble’ feature.

Win Potential


The range of bets offered in the Hellboy free slot provides players with varying levels of win potential. With the Hellboy maximum win up to 10,000 times your line bet, there’s always a high level of excitement. Play Hellboy in demo to train and win in real money mode.

Bets Range

The game allows you to set your wager per spin, with options ranging from a modest 0.01 credit for those seeking a cautious approach to the more daring 0.25 credits for those ready to embrace a higher level of risk and reward. You can test it via the Hellboy demo slot.

Hellboy Volatility

The high volatility of Hellboy means that wins may not be frequent, but when they do occur, they are often quite substantial.

Hellboy RTP

The RTP of 96.5% suggests that for every $100 bet, the average expected return is $96.50. This rate is comparatively high among online slots, indicating a reasonably rewarding player experience.

Game’s Hit Frequency

After testing 100 spins in the game’s demo mode, I found a hit frequency of approximately 30%. This means that, on average, every third spin resulted in a win.

Some of the biggest wins during my test period came from the Underworld Bonus and the Supermodel, with both features significantly contributing to the game’s overall win potential. The balance between risk and reward in Hellboy certainly makes for exhilarating gameplay.

First 100 Spins in Demo Mode

I decided to dive into the world of Hellboy by opting for the demo mode, eager to explore this thrilling slot game. As I began my adventure, I adjusted my bet per spin, opting for a moderate 0.25 credit to keep things exciting but not overly risky.

With my bet set, I clicked the ‘Spin’ button excitedly, watching the reels come to life. The anticipation was palpable as the symbols whirled before me, and I soon discovered that wins were far from guaranteed.

However, good fortune finally graced me when I thought luck might not be on my side. The Hellboy logo, the game’s ultimate prize, graced my screen with five matching symbols, and my winnings soared to an impressive 10,000 credits. Thus, play Hellboy for free!

Hellboy Verdict

Hellboy Online Slot provides a thrilling and immersive gaming experience. With a favourable RTP, captivating design, and enthralling features that increase win potential substantially, it guarantees excitement. High volatility adds to the intrigue, ensuring that willing risk-takers can reap significant rewards. Novice and seasoned players alike will find this game a spectacular entry into the world of online slots. Experience it to appreciate the hellish marvel that is Hellboy Online Slot entirely. So, I managed to play the Hellboy slot for free!
